Final answer:
The statement 'Haddock is an example of flatfish' is false. Haddock is not a flatfish; it is a groundfish with typical body symmetry and eyes on either side of its head, unlike the side-flattened body and same-side eye orientation of true flatfish.
Step-by-step explanation:
Haddock (Melanogrammus aeglefinus) belongs to the family Gadidae and is a groundfish, not a flatfish. Flatfish are a group of fish species that have a unique body structure, wherein both eyes are located on one side of the head, and they have a sideways flattened body. Examples of flatfish include halibut, flounder, and sole. Haddock, on the other hand, has a more typical fish body shape with a bilateral symmetry and eyes on both sides of its head.
